I have been running Linux17 and 18 for 5 or 6 months using BIBM. I have multiple OS's installed (they are all primary partitions as I have not limited primary partitions) but all are hidden in the Linux boot menu within BIBM. All of sudden, after running into a hiccup I had to reinstall Linux 18 and the GRUB menu popped up. It was never there before. I have tried everything I can find on Google to hide this darn thing with no avail.Is there something in BIBM that will not let me hide the GRUB menu?Any other tricks the Linux community doesn't know about that won't let me hide it?Thanks,Bob S

At the bottom outside the box is: Use the (up arrow) and (down arrow) keys to select which entry is highlighted Press enter to boot the selected OS, 'e' to edit the commands before booting, or 'c' for command lineThe highlighted entry will be executed automatically in 30 seconds.

Thanks for your help, Brian, but I have changed so many things in GRUB that didn't work. I had NOT tried the GRUB_HIDDEN_TIMEOUT=(blank), tho. I tried it and still got the menu.Here is my GRUB file:*********************************************# If you change this file, run 'update-grub' afterwards to update# /boot/grub/grub.cfg.# For full documentation of the options in this file, see:# info -f grub -n 'Simple configuration'

# Uncomment to enable BadRAM filtering, modify to suit your needs# This works with Linux (no patch required) and with any kernel that obtains# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"

It may also be helpful to see the actual grub.cfg file. There may be other commands being inserted that override the options you've set. Some of the automated sections can set a timeout depending on what they find, for example.

### BEGIN /etc/grub.d/40_custom #### This file provides an easy way to add custom menu entries. Simply type the# menu entries you want to add after this comment. Be careful not to change# the 'exec tail' line above.### END /etc/grub.d/40_custom ###

********************************************************I have tried setting all of these time delays to 0 with no avail as I'm sure grub-mkconfig is changing them. I have NOT tried deleting the 'menuentry' items (read this in Google somewhere) as I am too much of a newbie to Linux to try anything too exotic.

Brian'I changed GRUB_TIMEOUT=o to 0.1 and deleted the GRUB_DISABLE_OS_PROBER=true line ( I got this from another Google input) and I still get the darn menu. I have tried 0.0 and 0.1 in both of the timeouts with no avail. I did try your suggestion, tho just in case.Thanks for you assistance. If you think of anything else, please let me know. I'm getting ready to just reinstall the whole OS all over. I really don't want to go back to Windows 10.
